Picture show Device Overview YHWX series of computer harmonic elimination device is the company for the electricity sector and the user as often happens ferromagnetic resonance eliminator and voltage transformer (PT) even an explosion destroyed serious accident, and developed an intelligent harmonic elimination device. This device uses ARM processor as the core of the device processing elements, the device has stable performance, anti-interference ability and so on. Not only can eliminate the ferromagnetic resonance, can also over-voltage, single-phase ground to make alarm indication. Technical Specifications (1) Power supply: AC / DC80 ~ 250V, power consumption less than 15W;
(2) Ambient temperature: -45 ℃ ~ +50 ℃;
(3) Humidity: less than 90% RH;
(4) eliminate the resonant frequency: 17Hz (1/3 divider), 25Hz (1/2 divider), 50Hz (frequency), 150Hz (3 octave), 300Hz (6 octave). Device Features (1) applies to a variety of voltage levels, a variety of resonant frequency (1/3 frequency, 1/2 frequency, frequency, 3 octave, 6 octave) for a wide range;
(2) No tuning and debugging, boot automatically after running, maintaining a small amount;
(3) can be distinguished ferromagnetic resonance, over-voltage, single phase;
(4) automatically display and record single phase, ferromagnetic resonance occurs time and related parameters (resonance frequency, amplitude);
(5) 100 fault information can be stored for recall and display, down 100 years of data is not lost;
(6) can be configured RS485 communication interface, standard MODBUS protocol;
(7) All alarm relay contact output signals are provided |
